Flying through the plasmasphere to optimize low-energy ion measurements
The Juice flyby of Earth in August 2024 gave us the first chance to evaluate the performance of the Jovian Plasma Dynamics and Composition analyzer (JDC) in environments similar to those expected at Jupiter. JDC is one of the sensors belonging to the Particle Environment Package...

Empirical flare energy limits for the largest historical sunspots
Extreme solar particle events (ESPEs) reveal that the Sun can occasionally produce eruptions significantly more energetic than those observed in the modern era. These events are thought to originate from powerful coronal mass ejections (CMEs), typically associated with large sola...

Linking solar magnetism, extreme solar particle events and stellar superflares
The magnetic field of the Sun drives a wide range of eruptive phenomena, from small-scale nanoflares to large flares and coronal mass ejections. While direct observations of solar activity cover only the past few decades, indirect evidence indicates that the Sun can occasionally...

The parent bodies of Ryugu and Ivuna formed before those of other carbonaceous chondrites
Most carbonaceous chondrite (CC) meteorites contain abundant chondrules, millimeter-scale spherical inclusions of previously molten material. Ivuna-type carbonaceous chondrites (CIs) do not contain chondrules, nor do samples of the carbonaceous asteroid Ryugu. CIs and Ryugu share...

The SiO 2 abundance on the surfaces of the Moon and Mercury
The SiO2 abundance on rocky planetary surfaces is a key indicator for planetary crust composition and magmatic evolution. The Christiansen Feature (CF) in the mid-infrared provides a mineralogically grounded proxy for the abundance of SiO2. Here, we present a new experimental cal...

Abstract Protoplanetary discs emerging from collapsing molecular clouds are capable of forming planetesimals at the water snowline during both the cloud collapse and Class II disc phases; such a scenario could be responsible for creating the carbonaceous/non-carbonaceous (CC/NC)...
